A heterogeneous data fusion method for urban and rural integrated management with three-dimensional space information service

Abstract

The invention discloses a heterogeneous data fusion method for urban and rural integrated management with three-dimensional space information service. The method comprises the steps of three-dimensional information service system construction and heterogeneous data fusion. The three-dimensional information service system mainly comprises two parts, collecting and inputting of three-dimensional graph data and collecting and inputting of attribute data; Collection and input of three-dimensional graph data are oriented to a three-dimensional simulation model established for buildings, Bridge andgreenbelt in the field of urban planning. farmland and the like; the three-dimensional simulation model comprises geometric simulation, Physical simulation, Behavior simulation and biosimulation. Theinvention relates to a heterogeneous data fusion method for urban and rural integrated management with three-dimensional space information service. Two threads of data preloading and real-time loadingare adopted to schedule topographic data in parallel, so that data scheduling can better adapt to visualization requirements, different data sources are subjected to immunolabeling, a green channel is opened for later repeated feedback, and the data storage efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of data processing methods, in particular to a heterogeneous data fusion method for three-dimensional spatial information serving urban and rural integrated management. Background technique [0002] Spatial information system is a system related to the study of spatial location information. Spatial information system is an information system based on computer technology and network communication technology to solve the problems of data acquisition, storage, transmission and management analysis related to spatial information. Urban-rural integration is China's In a new stage of modernization and urbanization development, urban-rural integration is to take industry and agriculture, cities and villages, urban residents and rural villagers as a whole, make overall planning and comprehensive research, and promote the integration of urban and rural planning through system reforms and policy adjustments. The integr...
